Ireland's renewable penetration

In Ireland, renewable penetration on the grid is measured using the metric of system non-synchronous penetration (SNSP), which is essentially the ratio of intermittent renewable generation on the grid to demand at any given point.

Currently, Ireland’s grid can operate at up to about 70% SNSP, but that will need to reach nearly 100% by 2030 for the country to hit its target of an annual average of 80% renewable power on the grid. By increasing storage, grid operators will have the flexibility to take in excess renewable generation during low demand hours and export that energy when it is most needed during hours of low renewables output.…
